Cyanine5-C6-DBCO Usage And Synthesis
Uses
Cyanine5 DBCO (DBCO-Cy5) is a low-toxicity azide reactive probe (NIR fluorescent dye), for imaging azide-labeled biomolecules via a copper-free "click-through" reaction. Cyanine5 DBCO has no apparent cytotoxicity or animal toxicity and shows no damage to the physiological functions of cells other than the target cells (azide-labeled cells). Cyanine5 DBCO can be used to label and track cells in vitro and in vivo (Ex=635 nm, Em=650-700 nm)[1][2].
in vivo
Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Cell tracking in vivo[1][2]:
1. Seed cells onto 35-mm glass-bottom dishes at a density of 3×104 (varies by cell) in 2 mL of growth media.
2. Add Ac4ManNAz (50 μM, final concentration), incubate for 3 days (generate azide groups on the surface of cells).
3. Wash cells twice with DPBS (pH 7.4).
4. Anesthesia for mice, then inject cells (after Ac4ManNAz treatment) into the left lobe of the liver.
5. Inject Cyanine5 DBCO (25 μM, 200 μL) to tail vein (3 days post injection of cells into the liver).
6. Measure Cyanine5 DBCO fluorescence (Ex=635 nm, Em=650-700 nm). In vivo near-infrared fluorescence (NIRF) images is obtained with the in vivo imaging system.
